Oh, maybe nanobrain would know about this....
Well i've taken piracetam before daily, and definitely, notice my multitasking ability improved (among other things) - shit, its what i noticed the most. Once I was on the phone with someone, they were telling me a phone number to write down, and i had a friend in the same room with me, talking to me, and I was writing the number down as she said it, and listening to him FULLY, and at the same time, part of me was able to look at the whole thing and go "wow, this takes no effort!" - usually someone telling me what to write down my mind is more "linear" and kinda switches back and forth between hearing, and writing (sorta). This was like total parallel processing, and effortless.
Anyway, nanobrain - DMT and piracetam... holy fucking shit, um, "BAD"!! I couldn't narrow it down to anything else.. There were two times, once I took DMT orally w/harmaline during a piracetam daily thing, and oh god, when the DMT hit, it scared the SHIT out of me. No visuals, i heard my own voice come out of the radio speakers saying "wow" and other things, now, its normal to hear voices and stuff on DMT, but "something was not right". I felt like schizophrenic or something, i don't know how to explain it other than things in my head were getting routed to the 'wrong' area's. Panic. The solution? GBL! (actually it was 1,4-butanediol). I tried to stay calm and take my 1,4 bottle eye dropper thing and i managed to drip enough drops into a gelcap (how i would always take GBL/1,4, tasteless), for one capsule, as i was doing this my hands would start shaking almost violently like "something bad" was taking over, taking control, but not in a good way. I managed to quickly swallow this one capsule and knew i wouldn't be able to do a second. So I tried to sit calmly and wait. It worked enough eventually to cut the shit out..
That was the first time anything like it ever ever EVER happened on DMT, and I did not know why, i actually thought it was a 'bad DMT trip' or well i just had no explanation for it.
The next time it happened, was taking piracetam daily like before, smoked some DMT, not much, but as i inhaled the smoke... some "red alert" flag was set and i KNEW the feeling so i blew out the smoke as fast as i could, same shit, scary, "just NOT RIGHT", and stayed in one position until the effects of the DMT wore off (both of these times did not feel like DMT would normally).
This didn't happen all the time, on piracetam, but i dropped the piracetam totally, and well, DMT has been like DMT should be ever since.
I was not taking choline supplements with piracetam, maybe that was the issue..
But, as i'm a DMT addict/freak, um, of course, i quit piracetam for good then. All better

. But christ piracetam FUCKS with DMT! Other psychedelics might be enhanced or whatever, but as DMT works differently (sorry, no scientific proof i can give anyone, hehe.. only DMT freaks would understand, i guess lol) whoa...
DMT is now DMT all the time everytime (which is always = great). I'm curious if it was from taking piracetam without choline supplements... but really who knows.. All i know is other DMT freaks have said, piracetam really fucks with the DMT experience although never read about anyone experiencing what I did those couple times. Only GBL/1,4-b / ghb would put an immediate stop to it (forget benzo's etc).
